Used primarily in pharmaceutical research as an intermediate in the synthesis of histamine H2 receptor antagonists. It plays a key role in developing compounds that reduce gastric acid secretion, making it valuable in the treatment of peptic ulcers and gastroesophageal reflux disease (GERD). Its structure supports the design of molecules with improved bioavailability and receptor selectivity. Also utilized in the development of novel drug candidates due to its ability to enhance binding affinity to target receptors.
